PhysDiff: Physics-Guided Human Motion Diffusion Model

Understand

Denoising diffusion models hold great promise for generating diverse and realistic human motions.

• However, existing motion diffusion models largely disregard the laws of physics in the diffusion process and often generate physically-implausible motions with pronounced artifacts such as floating, foot sliding, and ground penetration.
• This seriously impacts the quality of generated motions and limits their real-world application.
• To address this issue, we present a novel physics-guided motion diffusion model (PhysDiff), which incorporates physical constraints into the diffusion process.
